Bestandsundersøkelser og forslag til regulering av loddefisket i området lsland-Grønland-Jan Mayen i 1979
(Journal article, 1979-10-15)Sommeren 1978 begynte norske ringnotfartøyer å fiske lodde i området mellom Jan Mayen og Grønland. Dette er lodde som gyter ved Island om vinteren, og som beiter i området mellom Island, Grønland og Jan Mayen om sommeren. ... -
Importance of the swimbladder in acoustic scattering by fish: A comparison of gadoid and mackerel target strengths
(Journal article; Peer reviewed, 1980)Previous determinations of the swimbladder contribution to the fish backscattering cross section have been hindered by ignorance of the acoustic boundary conditions at the swimbladder wall. The present study circumvents ... -
Torsk, hyse og havforskarar
(Journal article, 1980)Trålfisket etter torsk og hyse i Barentshavet har vore uvanleg rikt hittil i år, og dette har overraska mange på bakgrunn av dei låge fangstkvotane for 1980. Har havforskarane tatt feil i vurderingane sine av bestanden? I ... -
Averaging of fish target strength functions
(Journal article; Peer reviewed, 1980)A general model for averaging the acoustic target strength functions of fish is stated in calculable form. It accounts for the influences of the distribution of generally coupled spatial and orientation states of fish, ... -

Comment on ''Some frequencies of underwater noise produced by fishing boats affecting albacore catch'' [J. Acoust. Soc. Am. 66, 296–299 (1979)]
(Others, 1980)An alternative explanation for the observations analyzed by Erickson is offered. Differences in catch-related success of boats participating in the West Coast Albacore fishery are attributed to the low-frequency content ... -

The influence of wind-induced bubbles on echo integration surveys
(Journal article, 1981)An investigation of attenuation of acoustic energy caused by gas bubbles in the surface layers has been carried out. This was done primarily to study the effect on echo integration of fish abundance when using hull-mounted ...
